Application med July 16,1907, serial No. scares To all lwhom 'it may concern:

Be it known that we, PAUL SCHMIDT, a subject of the Emperor of Germany, and ADoLrHE Dnsennz,A a citizen of Switzerland, residing at Hanover, Germany, have invented certain new and useful Im rovements in Soaking-Fits, of which the ollowing is a full, clear, and exact description.

its in which in gots are placed While t ie temperature throughout the same is equalized prior to assinr them through the rolls and the object o? -the invention is to rovide means whereby the temperature of t e pits may be regulated to avoid chilling :whereby the entire char e or 'cast of the, ated Without loss and without considering thev capacity of the rolls. These objects are attained' by an apparatus of the character illustrated in the accompanying drawin s and the invention consists in certain nove features of the same, as will be hereinafter first fully described and then particularly pointed out in the claims.

In the drawings, Figure 1 is a transverse section ltaken on the line A-B of Fig. 3 While Fig. 2 is a longitudinal section taken on the line C-D of Fig. 3, Fig. 3-being ak plan view.

placed, the pits being arra to'thedrawings by letter, c', al, denote the pits in which the ined in may be desired. he pits of eac pair communicate and in front of each pair 1s a heateach provided with a heating device These heating. chambers are desigends, the pits communicate with a common Hue u which carries the Waste gases to a recuperator t from which they may escape through a discharge flue u Y rovided lwith a damper or valve fw. The c ambers are in' dependently heated .and are provided with separate air and gas sup ly pipes so that according to the cihtate the 'adjustmentfthe actuating mechanism for the supply-controlling devices is located above ground out of th Way of the cranes. Air is supplied to the recuperator t through a pipe whence it asses in a highly lecting chamber of the ingots' and' limits.

The gas is supplied through the vpipe o from which it passes tothe heating chambers through separate branch pipes controlled by regulating valves dd d arranged in an open space a underground. The valves are operated by act'uatmgdevices o p whi'ch vare connected with the respective va vede by chainsl or cords and are arranged above ground over thereservoir r. The as and air supply ipes or iiues enter the coilectin spaces o r c ambers'eg, respectively, the sai collecting chambers eing provided in their .rear walls with nozzles or ports s s Wlich are in alinement and through which the mingled air and gas ass to the res ective heating chambers. Flic gas passes lrom the charnber e through the nozzle s under such pressure that it asses .in a compact current through the air chamber f and the nozzle s so as to carry the air with it and become intimately mixed themwith upon its entry into the pit.

By the arrangement described and shown the heating will be affected immediately by any variation in the supply of gas or air, the result being'that the combustion process c a'n' be regulated. andl adjusted within wide The pits can, consequently, be divided into a number of small uint groups which can be separately' heated and the whole plant can be managed in a manner most suitable to the material o'l: 'the ingots. As the gas and air supply of eachchamber can be separately adjusted and the controlling mechanism of' all the chambers-are arran ed. close together above round andout o the Way of the cranes, it olloWs that the heating of each chamber ,may be regu# lated from one point according to the re' quirements of the in got therein. By 'nnitin tWo pits in a single chamber, we are enable to heat the ingots therein uniformly with a series ol? heating chambers therefor, an air ue passes, a resery'eir into which seid said Valves ell arranged over the reservoir.
